cool story
An intriguing story. The crucifying was a little bit much for me, but that's all the story, so it's ok. The demon looked very cool, I would go with a different voice - subtitles should be for people who can't hear it, so those of us who can... should be able to understand your characters. Go with a good filter that is demonic but audible.
The excessive tweening was rather off-putting. When the characters glided away from the funeral and then the shovel floated around without someone on it. You should use more frame by frame animation to inspire some life into your story. The audio was pretty good - I'd suggest seeking out some of newgrounds voice talent, but if your actors show some improvement that's ok.
this has a lot of potential, and the still art was cool, but the tweening and lack of shading was a turn off. Everything was fall too flat - maybe show a little more depth since you're going for a more realistic look. Shading, scenery, different colors to show how far away things are. Use the brush tool a little more maybe so everything doesn't look so "line-y." My art teacher told me "No no no... there are no lines in real life..." it's more where two colors converge together. (too indepth, I know :p ) But great job, good luck on the full version, hope to see it sometime soon!
